GWI said in an email to SocialTimes:
As a smartphone generation, millennials place a strong premium on the speed of communication offered by messaging apps; as many as seven in 10, in fact, say they use instant-messaging services because they are quicker than SMS or social media.
Globally, WeChat is the most popular IM service for 17-31s, reflecting its massive success in China (where 60 percent of millennials are using it). Outside of China, though, it’s Facebook Messenger (35 percent) and WhatsApp (32 percent) that compete for dominance — with Messenger typically doing well in mature markets and WhatsApp posting its best figures in fast-growth countries.
Despite hitting the headlines, Snapchat is still a minor force (8 percent). But this global figure masks major peaks in certain markets: One-quarter of millennials in Ireland are using Snapchat, as are one-fifth in the U.K. and U.S.
